Don't use bleach in your laundry unless your whites are all 100% cotton. Bleach yellows anything that has polyester in it. And most whites do anymore. I don't even have bleach in the house. You can accidentally mix it with a cleaner or other compound and the fumes could kill you. That's probably why Dawn says don't mix with bleach. Many of our problems today are cause by being 'over' clean. Bodies simply do not have a chance to build up an immune system. I grew up on a farm, with an outhouse. Hot water came from a teakettle on a stove, or in the woodstove kettle for using in the washing machine. My grandmother's all lived into their mid 90's. My mother turns 95 in two weeks. Please put the bleach away. My husband uses ACV for killing weeks, he refuses to use killer Round Up. Yes, the white vinegar in a final wash water softens clothes. And I made two balls out of wool yarn for in the dryer. So we always have soft towels. The rest I dry on the line. Another thing bad for those with immune system problems, all the fragrance scents out there. And plug ins are the worst, they wax your walls and furniture. I cannot stand to be in a home that uses them, can't breathe.
